PURPOSE: To heighten the electromagnetic shielding effect.

CONSTITUTION: A series of conductive coating is formed on the inner walls of respective contact holding holes 12, 14 of a female and a male connector main bodies 1, 6 as well as 4 the surface sides of the connector main bodies. A female contact 11 for earthing and a male contact 13 for earthing connected with the earth circuits of printed substrates 5, 9 are set and inserted in the respective contact holding holes. By bonding the female contact 11 for earthing and the male contact 13 for earthing, the conductive coating parts of both female and male connector main bodies 1, 6 are electrically connected even if the connector main bodies do not touch each other. Also the earth circuits of the printed substrates 5, 9 are surely connected with each other.
